FAQ

Is this calculator really free?

Yes. No account, no email, no payment. The site is funded by advertising.

How accurate is the result?

It's a mathematical estimate based on the dimensions and weights you enter. Always confirm the final loading plan with your carrier — real loading also depends on weight distribution, packaging, and transport safety rules.

Do you store my product data?

No. Product, carton and pallet values you type are used only to run the calculation and are never saved to a database.

Which containers are supported?

20 ft, 40 ft, and 40 ft High Cube, with standard internal dimensions and payload limits.

What does 'limiting factor' mean?

It tells you which constraint capped your load — weight, volume, floor space or stack height — so you know what to optimize first.
